The following is a good recipe for preparing grafting-wax, the chief 

 object of which is to exclude the air from the cuts on both stock and 

 scion: — 4 lbs. resin, 2 lbs. beeswax, 1 lb. mutton tallow. Dissolve over 

 slow fire and apply warm. The wax should not be made hard enough to 

 crack after being applied. 



Horse labour is a necessary item on the dairy farm, and should com- 

 mand much attention from the manager. If its efficiency drops the 

 profits of the farm are decreased, and the iprofits from the cows must 

 bear a loss in the horse labour item. It is seen then that successful 

 dairying is not making a success with cows alone, but profitably com- 

 bining a number of factors. Man, labour, and crop yields per acre are 

 other important factors that can be controlled to a considerable extent 

 by the manager. 



AN EXPERIMENT TO SHOW EFFECT ON QUANTITY 

 AND QUALITY OF MILK PRODUCED BY (JOWS 

 WHEN MILKED AT EQUAL AND UNEQUAL 

 PERIODS. 



The results of two dairy experiments conducted at Offerton Hall, 

 extending from May, 1912, until April, 1915, are here reproduced. 

 The Durham County Council has set aside a sum not exceeding X120 

 a year for these investigations which it places at the disposal of Arm- 

 strong College, Newcastle-upon-Tyne. The extracts are from the 

 Offerton Bulletin, No. 5 Report on further Experiments on the 

 feeding of Dairy Cows at Offerton Hall, by Frank P. Walker, 

 M.Sc, F.H.A.S., adviser in agriculture to the above College. — Editor. 



The exigencies of the new milk txade in many cases involve a great 

 difference in the times between morning's and evening's milking periods. 

 Apart altogether from the general feeding and management of a milk- 

 ing herd this difference in the time of milkings makes a considerable 

 difference to the quality of the milk. It may be generally said that the 

 longer the period between the milkings, the poorer the quality of the 

 milk. Other experiments have shown that when the periods between 

 the milkings more closely approximate than is the usual practice, the 

 quality of the morning's and evening's milk is very similar. A previous 

 experiment at Offerton Hall in 1905 confirmed this, but the experiment 

 only lasted for a period of eighteen days. The object of these experi- 

 ments was to see how far deductions based on a short trial would be 

 confirmed when the experiments lasted over a considerably longer 

 period, the cows being reversed during the later experiment. 



For this experiment not quite so many cows in full milk were 

 available as is usual, and it was felt that one or two of the stale milkers 

 might not continue tO' milk throughout the experiments. As a fact it has 

 to be recorded that one cow had fallen to a gallon a day by 2nd 

 September, and was only giving 2 quarts per day at the end of the 

 experimental period on 22nd September. 



Experiments U and V lasted from 1st July to 22nd September 

 inclusive durinsf the summer of 1911.
